7 10 Claims. (CI. 98-98) Among the principal objects which the present invention has in view are: to provide a ventilator which may be universal to windows of various sizes; to enable the ventilator to be attached with minimum difliculty; to utilize existent hardwareon the window frame for attaching the'ventilator; to enable the ventilator to be readily attached or removed if so desired; to provide for attachment of a shade without obstruction to airflow through the louvres of the ventilator; to protect the shade from rain and other damaging causes while air is admitted through the louvres of the ventilator; to substantially seal the space between the ventilator and the sash; to cause, entering air to be directed upwardly and none permitted to enter in a downward direction; and to secure simplicity of construction and operation.

Description v This particular invention is directed to a ventilator comprising a telescopic construction, whereby it may be fitted and be adjusted to windows of various widths. As seen in the drawings, the ventilator is more especially adapted for positioning at the upper part of a window frame 10 in the plane of the inner sash runway molding 11,'so as to be within the building or room. It will be understood that the upper sash 12 of a window is usually-in a plane. outside of the plane for the inner sash, and therefore said upper sash may be completely closed when desired. When it is intended that air shall be admitted through straight edge of the other as shown Suitable the ventilator, the said outer and upper sash is lowered until its top rail is opposite the lower edge of the ventilator. This assumes or allows an even flow of air at all times to enter into a building or room, and provides further for the heated atmosphere in the ceiling area to escape outwardly through the ventilator.

Said ventilator is provided with a bottom or base 13 extending cross-wise of the window frame (longitudinally of the ventilator) which overlies the channel or runway for the lower sash and has an upturned flange 14 substantially at the inside plane of the outer sash so as to meet the said upper rail thereof and form a closure with respect thereto entirely across the window. This base 13 with its flange 14 prevents entry of air below the ventilator and thus avoids any downwardly directed currents of entering air. Also; in the event of bad weather such as rain or snow, said base in this instance serves to prevent water from entering the room.

The ventilator is preferably constructed in sections 15, 15 longitudinally slidable with respect to each other, one overlapping the other so that the same may be applied to window frames of diiferent widths. Any suitable longitudinal channeling of one section to slidably retain the other may be utilized, such as the reverting of the marginal edges of one section to overlie the air inlet openings or louvres 16 are provided in each section, these openings or louvres being formed by a slitting and deflection of the metal with the slope of the metal at the slits inclining inwardly and upward to correspondingly direct the flow of air in an upwarddirection on entering the room.

Referring now to the specific construction and mode of attachment shown in the preferred embodiment of- Figures 1 to 4-, each section 15 is provided withan outer end flange 17 directed inwardly with respect to the window frame and extending longitudinally of the window frame for the height of the ventilator. Near the upp end of said flange 1'7 and in the plane thereof is provided a tab 18 which also projects inwardly of the window. This tab is, in manufacture, placed at appropriate distance from the upper edge ofv the ventilator and made of correct dimensions to enable it to be inserted behind and through the usual off-setbearing portion 19 of the shade fixture 20. After this tab is inserted, it may be bent to prevent inadvertent removal or displacement of theventilator. The invention accordingly contemplates the utilization of shadefixture hardware to be found in position in most windows.

Preferably, however, the flange 17 of the ven-r tilator sections 15, 15 has a bearing 22 stamped or otherwise provided near its lower part, thereby enabling the shade 21 to be supported crosswise of the window without obstructing the flow of air through the ventilator and without being subject to the possible damage from rain or other causes which would result from the shade being opposed to the ventilator openings or louvres 16. It also allows for the window to remain open at all times,

especially during the night when the shade is usually drawn, in this instance owing to the location of the shade or shades, rattling or flapping is thereby prevented.

Furthermore, in order to obtain a fixed positioning of the ventilator, if desired, said flange 17 of each section 15 may be provided with a plurality of holes 23 therein enabling the user to drive in a nail or two, or screws if desired. Support and positioning of the ventilator may be entirely by nailing or screwing the same if so desired. A ventilator for attachment by nails only, is shown in Figures 5, 6 and 7, and diflers substantially from the construction above described only in the omission of the tabs 18.

It. is further to be understood that my invention contemplates other modes of window hardware for supporting the ventilator. In Figure 8 there is shown means enabling the ventilator to be hung from. the shade-bracket bearings 20 by insertion of pintles into said bearings corresponding to pintles of a shade. Inj'this view, a hanger bracket 25 is shown attached to the ventilator, spaced slightly inward from the flange 17. The outer end of said bracket 25 carries a pintle 26 directed toward the end of the ventilator. This pintle will enter the bearing portion 19 of the fixture. In this construction, the inclusion of a shade mounted in the ventilator shade-bearings 22, will hold the sections 15 properly slid to outermost position permitted by the window frame, and thus retainthe pintles 26 seated. Other means, such as a set-screw 27 passed through one section 15 and bearing against the other section 15,- may be employed for retaining the sections fully extended and secure the ventilator against falling should a shade accidently become disengaged from its resting place in the shade-bearings 22.
